## Error - 81010

### There was an internal error while processing a Function

Studio could not invoke the Function service.

#### Possible Causes

- The Function timed out or did not include `callback()`
- There may be an issue with Twilio Function Service

#### Possible Solutions

- Verify your Function calls `callback()` to avoid timeouts
- Check your Function logs for runtime errors
- Ensure you're returning the correct status code
